Brain Confidence: How Our Neurons Make Decisions

Great video in this article from the Big Think.

Neuroscience research is revealing how the chemistry and architecture of the brain make decisions for us, and how the brain's reaction to decision-making is based on confidence. Researchers has shown that a networked, hierarchical process is strung out across the brain to achieve these functions, even while specific neuron clusters are more active than others in helping us make decisions. 

While human-focused research uses leading-edge brain scans, some scientists are studying the neurology of decision-making in rodents because their brains are evolutionarily similar to those of humans.
